I m taking bisoprolol, amlodipine, losartan, bendromethafluazide, losartan and warfarin Since starting amlodipine recently my left ankle swells all the time, I have aching joints, breathlessness, and can hardly walk due to leg pain. I also sleep a lot, about 11 or 12 hours a day. I m 64 years old. Is this normal?
